Level 92 Poisonous Concoction Pathfinder^3.22

Notes

Getting this version of the build to its final form should not cost more than around 5 div, maybe less depending on the prices in trade. It's relatively cheap and powerful, which is the point.

Some explanation:

1. Follow the leveling trees up to the initial Level 71 (Campaign Complete) version, which assumes you have collected all extra passive skill points during the campaign.
After that, match each progressive Tree, Item Set, and Skill Set as you go. By that I mean, and for example: Level 71 (Campaign Complete) has a Tree, Item Set, and Skill Set, all named accordingly.
Same for Level 84 (Early Maps), Level 91 (Change to Clusters) etc. You must select the same version in all the applicable dropdown lists to get the build at that point, and for it to make sense.

2. Kill all bandits. Select whichever Major and Minor gods you prefer. I normally go with Arakaali for the chaos degen protection, and fully specced Abberath for Burning Ground immunity.
Ryslatha can also be a very strong option, as it helps refill our life flask/s.

3. The passive skill point progression is a suggestion only. Do whatever suits your playstyle. You are aiming to hit the structure of the final build, which allows 5 auras.

4. The leveling itemization is also an example only. You will have to balance your resistances as you go with what items you can find. Get the highest linkage armor you can as a priority.

5. You can transition to Poisonous Concoction at level 12 if you can get the gem. Before then I suggest you use a bow + quiver with Caustic Arrow, and possibly buy a Quill Rain and run Rain of Arrows for a while.

6. I've added an endgame rare Cobalt Jewel just to show what is possible with the various mods. It's very helpful (particularly the Corrupted Blood immunity), but it's not actually necessary.
Not using one - if mana reservation allows it - will save you 2 skill points/levels.

7. The mana reservation balance of the final build is very tight, and it could be changed by league specific mechanics, and/or nerfs and buffs. As always, work around what is required.

8. The final version here is a good point to stop spending and begin farming for currency as it's fast, reasonably tanky, and does enough damage to easily clear red maps (or whatever mechanic you enjoy).
